I have the same dryer. I bought a universal diffuser at Ross that works fine. It is a pretty powerful dryer though
. I have to push the diffuser back on while I'm drying at least once because the dryer blows strongly and it will pop off...really not that big of a deal as I'm used to it. I'm eyeing that babyliss dryer though since its smaller and the warranty on it is 4 years. The one I have has a 2 year warranty, which is good. I have had no problems with it. I can't remember what I paid for it now because it was on sale plus I had a coupon code and that's why I splurged, definitely a good investment for me. I use my dryer often, every other day.
